Airborne 12.09.16

AD NUMBER: 2010-26-08

SUMMARY:We are adopting a new airworthiness
directive (AD) for the products listed above. This AD requires a
detailed inspection of the entryway door movable ceiling panel for
pin migration at either end of the hinge assembly and damage to the
pin; a detailed inspection for correct crimp at both ends and
damage to hinge stock; a detailed inspection of the ceiling area
for any visible cosmetic and/or tie-rod chafing that could be
caused by a migrated hinge pin; a detailed inspection for wire
damage and/or breakage; and other specified and corrective actions
if necessary. This AD results from reports of fault messages caused
by improperly crimped hinge pins coming into contact with wires and
causing damage. We are issuing this AD to detect and correct
improperly crimped hinge pins, which could damage tie rods
and
wire bundles, causing shorts in many systems, including the spar
fuel shut-off valve, oxygen mask deployment, and burned wires,
which could be an ignition source in a hidden area of the
airplane.
